Hi, thanks for your kind words and interest
These terms of use are specifically against any form of exploitation, advocacy, or apology in favor of harmful activities against others.
I can understand that in your game the PCs can be evil characters, but if you advocate, defend and encourage them to describe in detail their evil against others and use hate speech as its philosophy (defending those acts as something positive or desirable, without a critical view against them), I would ask you to please do not use them.
If, on the other hand, there is a critical value and it is clear that what you are exposing is something harmful and undesirable, either as criticism or parody, I could understand and accept your use of them.
